Graph

The graph report will render all returned nodes, relationships and paths in a force-directed graph layout. This includes collections (lists) of these objects.

The library react-force-graph is used to create the visualizations. Depending on your browser, the visualization should be able to handle drawing 1000-3000 nodes/relationships with custom styling options.

The graph layout contains an extensive set of features, including:

Drag and drop nodes.
Custom node/relationship styling.
Tooltips/inspect window on nodes/relationships.

Examples

Basic Graph

MATCH (p:Person)-[a:ACTED_IN]->(m:Movie)
WHERE m.title = 'The Matrix'
RETURN p, a, m

Virtual Graph (apoc is required)

MATCH (p:Person)-[:ACTED_IN]->(m:Movie)<-[:ACTED_IN]-(p2:Person)
WHERE m.title = "The Matrix"
RETURN p, p2, apoc.create.vRelationship(p, "KNOWS", {}, p2)

Advanced Settings

Name	Type	Default Value	Description
Node Color Scheme	List	neodash	The color scheme to use for the node labels. Colors are assigned automatically (consequitevely) to the different labels returned by the Cypher query.

Node Label Font Size	Number	3.5	Size of the labels drawn on the nodes.
Node Size	Number	2	Default size of a node in the graph visualization. This size is applied if no custom size styling is defined and no Rule-Based styling is active.
Node Size Property	Text	size	Optionally, the name of the node property to map to the node size. This lets you define sizes on a node-specific level, if you have a property that directly maps to the numeric size value.
Node Color Property	Text	color	Optionally, the name of the node property to map to the node color. This lets you define colors on a node-specific level, if you have a property that directly maps to the HTML color value.

Animated Particles on Relationships	on/off	off	If enabled, draw relationships with animated particles on them, moving in the direction of the relationship.
Arrow head size	Number	3	Use this to set the length of the arrow head, size is adjusted automatically. If 0, no arrow will be drawn.
Background Color	Text	#fafafa	The background color of the visualization.
Layout (experimental)	List	force-directed	Use this to switch from the main (force-directed) layout to one of the two experimental layouts (tree/radial). For the experimental layouts, make sure your graph is a DAG (directed acyclic graph).
Enable graph exploration	on/off	on	Enables basic exploration functionality for the graph. Exploration can be done by right clicking on a node, and choosing 'Expand' to choose a type to traverse. Data is retrieved real-time and not cached in the visualization.
Enable graph editing	on/off	off	Enables editing of nodes and relationships in the graph from the right-click context menu. In addition, lets users create new relationships with existing types/property keys as present in the database.
Show pop-up on Hover	on/off	on	if enabled, shows a pop-up when a user hovers over one of the nodes/relationships in the visualization. The pop-up contains the label and properties of the node/relationship.
Show properties on Click	on/off	on	if enabled, opens up a window when a user clicks on one of the nodes/relationships in the visualization. The window contains the label and properties of the node/relationship.
Fix node positions after drag	on/off	on	If enabled, locks in (freezes) the node positions after a user drags them.
Drilldown Link	Text (URL)	(no value)	Specifying a URL here will display a floating button on the top right of the visualization. This button can be used to drilldown into a different tool (e.g. Bloom) so that the graph can be explored further. Dynamic Dashboard Parameters (e.g. $neodash_person_name) can be used in these links as well.
Hide Selections	on/off	off	If enabled, hides the property selector (footer of the visualization).
Auto-run query	on/off	on	when activated automatically runs the query when the report is displayed. When set to `off', the query is displayed and will need to be executed manually.
Report Description	markdown text		When specified, adds another button the report header that opens a pop-up. This pop-up contains the rendered markdown from this setting.
